MOUNTAIN VIEW, CA--(Marketwire - April 03, 2012) - Hansen Medical, Inc. (NASDAQ: HNSN), a global leader in flexible medical robotics and the developer of robotic technology for accurate 3D control of catheter movement, today announced that it filed a shelf registration statement on Form S-3 with the Securities and Exchange Commission ("SEC"). Although the registration statement relating to these securities has been filed with the SEC, it has not yet become effective. Upon the effectiveness of the registration statement, it will replace the Company's previous shelf registration statement that would otherwise expire early next year. While the Company has no current plans to issue any securities under the registration statement, it is the Company's practice to maintain an effective and up-to-date shelf registration statement, and this new filing will provide the Company with the opportunity for additional financing capacity to access capital markets in order to respond to future financing needs and business opportunities.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy these securities, nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.

About Hansen Medical, Inc. Hansen Medical, Inc., based in Mountain View, California, develops products and technology using robotics for the accurate positioning, manipulation and control of catheters and catheter-based technologies. The Company's Sensei® X Robotic Catheter System and Artisan Control Catheter were cleared by the U.S. Food and Drug Administration for manipulation and control of certain mapping catheters in electrophysiology (EP) procedures. This robotic catheter system is compatible with fluoroscopy, ultrasound, 3D surface map and patient electrocardiogram data. In the United States, the Sensei System is not approved for use in guiding ablation procedures; this use remains experimental. The U.S. product labeling therefore provides that the safety and effectiveness of the Sensei X System and Artisan Control Catheter for use with cardiac ablation catheters in the treatment of cardiac arrhythmias, including atrial fibrillation (AF), have not been established. In the European Union, the Sensei X System and Artisan Control Catheter are cleared for use during EP procedures, such as guiding catheters in the treatment of AF, and the Lynx® Robotic Ablation Catheter is cleared for the treatment of AF. The Company's Magellan™ Robotic System, NorthStar™ Robotic Catheter and related accessories, which are intended to facilitate navigation to anatomical targets in the peripheral vasculature and subsequently provide a conduit for manual placement of therapeutic devices, have undergone conformity assessment and CE marking and are commercially available in the European Union.

In the U.S., the Magellan™ Robotic System, the NorthStar™ Robotic Catheter and accessories are the subject of a current filing with the FDA and are not commercially available. Additional information can be found at www.hansenmedical.com.
